Abstract :
Conductors are one of the important components of the overhead line that role to distribute electricity from power plants to substation up to consumers. The conductor ranged between two transmission towers will not follow a straight line, but because of the weight itself will curve downward which is called sag. The Kemayoran-Ancol route transmission line passes through the city, it is necessary to calculate the carrying capacity of the Current Conductivity Capability (CRC) that can be received by the conductor and the maximum ambient temperature of 40oC, so can obtain the maximum sag value. The method used is quantitative. Current currents and ambient temperature cause an increase in temperature at the conductor so that the conductor expands and increases in length so sag will increase, but the tension on the conductor is inversely proportional to sag. Each increase in temperature of 1oC will increase sag by 0.41% and the tension of the conductor decreases by 0.41%. The results of the research that the maximum sag value is 8.80709 m so the sagging still qualify the standard conductor clearance under the conductor of high voltage electric power transmission lines by 5 meters according to SNI 04-6918-2002
